Test sections in high-modulus asphalt: a comparative experiment with ten variants

In April 2006, test sections in high-modulus asphalt were constructed on the right-hand lane of the Brussels-Antwerp motorway, which is intensively used by heavy goods vehicles. The test site stretches over a length of 1.6 km and comprises nine variants of high-modulus asphalt and one reference section with conventional asphalt concrete. The variants were chosen after extensive research in the laboratory. Among the parameters tested in the variants are the type of mixture (stony or sandy skeleton), the type of binder, binder content, and with or without the addition of recycled materials. The work on site was carried out in successive stages including the removal - by milling - of existing layers to a depth of 12 cm, the laying of a 9 cm thick binder course in high-modulus asphalt, and the application of a 3 cm thick surface course in stone mastic asphalt (SMA). With a view to monitoring the behaviour of the test sections, the site was equipped with temperature gauges and loop sensors to record climate and traffic data. Preliminary results are described, particularly with respect to the feasibility of the process. For the covering abstract see ITRD E157233
